supercluster Files

Adds a flat tile envelope matching geojson-vt v5's getTileRaw, and moves TypeScript declarations into the package.

API changes

• New getTileRaw(z, x, y) returns the same tiles as getTile, but with each feature's coordinates inline — {type: 4, x, y, tags} instead of {type: 1, geometry: [[x, y]], tags}. Every clustered feature is a single point, so this is geojson-vt's raw envelope narrowed to its lone-point variant, and consumers that unwrap geometry[0] immediately can skip two array allocations per feature. getTile is unchanged.
• TypeScript declarations ship with the package. Remove @types/supercluster if you have it installed.

TypeScript migration

The bundled declarations cover the same surface as @types/supercluster@7.1.3, with three differences:

• Breaking for @types users: types are named exports rather than members of a merged Supercluster namespace. Replace Supercluster.Options<P, C> with an import type {Options} from 'supercluster'. Using Supercluster<P, C> itself in type position still works. This matches how geojson-vt's declarations are shaped.
• Tile tags are typed | null | undefined. Supercluster passes each input feature's properties through verbatim, so tags is null when the input had properties: null and undefined when it omitted the member — both need a guard before use. The old declarations claimed tags was always present.
• load() accepts MultiPoint features as well as Point, matching the support added in v9.0.0.
